70% of P0269 cases are fixed by replacing this part
Damaged, corroded, or loose wiring or a faulty connector to the cylinder 3 fuel injector can cause an incorrect voltage reading.
25% of P0269 cases are fixed by repairing the wiring or connector
A rare internal fault within the engine computer's driver circuit for cylinder 3's fuel injector can cause this code.
5% of P0269 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Visually inspect the wiring and connector for cylinder 3's fuel injector for any obvious damage, fraying, or corrosion.
- Listen to the cylinder 3 injector with a stethoscope to confirm it is clicking, indicating it's receiving a pulse.
How to Diagnose P0269
- 1Check for other related codes, especially P0303 (Cylinder 3 Misfire) or P0203 (Cylinder 3 Injector Circuit Open).
- 2Visually inspect the wiring harness and connector for cylinder 3's fuel injector for any signs of damage, corrosion, or loose connections.
- 3Use a stethoscope to listen for a clicking sound from the cylinder 3 injector with the engine running; a lack of click indicates no pulse.
- 4Use a noid light to check for a pulse signal at the cylinder 3 injector connector while cranking the engine.
- 5Measure the electrical resistance of the cylinder 3 fuel injector with a multimeter (compare to specifications or other injectors).
- 6If possible, swap the cylinder 3 fuel injector with an injector from another cylinder and see if the code moves to the new cylinder.
P0269 on Popular Vehicles
Ford F-150
2004-2024Ford F-150s, particularly those with direct injection engines, are prone to fuel injector failures. The P0269 code often indicates a failed injector that needs replacement.
75% fixed by replacing the fuel injector
Chevrolet Silverado
2007-2024On Chevrolet Silverado trucks, P0269 is frequently caused by a faulty fuel injector. Inspecting the wiring harness for chafing or rodent damage is also a good first step, but injector replacement is a common fix.
70% fixed by replacing the fuel injector
Honda Accord
2003-2024Honda Accord models can experience P0269 due to a failed fuel injector. Electrical testing of the injector and its circuit is crucial to confirm the injector itself is the problem before replacement.

Frequently Asked Questions
What does P0269 mean?
P0269 indicates the engine's computer has detected an electrical problem with the fuel injector for cylinder 3, specifically that the circuit voltage is too low.
Can I drive with P0269?
Limit driving, fix within a few days. A misfiring cylinder can cause significant damage to your catalytic converter and other engine components if ignored. Drive only for essential, short trips.
Will P0269 clear itself?
No, P0269 will not clear itself. This code indicates a hard electrical fault or a failed component that requires diagnosis and repair. The Check Engine Light will remain on until the underlying issue is resolved.
How do I fix P0269 myself?
Start by visually inspecting the injector wiring. If the wiring looks good, test the injector's resistance and check for a pulse with a noid light. If the injector is faulty, you will need to replace the cylinder 3 fuel injector. This often involves removing the fuel rail.
How much does it cost to fix P0269?
DIY repair typically costs $50-$300 for a new fuel injector. Professional repair at a shop will cost $250-$700, which includes parts and 1-2 hours of labor.
P0269 keeps coming back - why?
If P0269 keeps returning, it points to an undiagnosed issue. Common reasons include a faulty wiring harness that was not fully repaired, a poor connection at the injector, or a rare problem with the Engine Control Module (ECM) itself.
Will P0269 fail emissions/smog test?
Yes, P0269 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on, especially for a misfire-related code, is an automatic failure in most jurisdictions.
What's the difference between P0269 and P0303?
P0269 specifically indicates an electrical fault with the cylinder 3 fuel injector circuit. P0303 indicates a general misfire on cylinder 3, which can be caused by many things, including a faulty fuel injector, spark plug, ignition coil, or compression issue. P0269 is a more specific diagnostic code pointing directly to the injector's electrical health.
P0269 on Ford F-150?
On Ford F-150s, P0269 most commonly points to a failed fuel injector for cylinder 3. While wiring issues can occur, especially with rodent damage, the injector itself is the primary suspect. Replacing the injector typically resolves the issue.
Questions to Ask Your Mechanic
Did you test the resistance of the cylinder 3 fuel injector and compare it to specifications?
Good answer: Yes, the resistance was X ohms, which is outside the normal range of Y-Z ohms, confirming an internal fault in the injector.
What did you find when checking the wiring and connector for the cylinder 3 injector?
Good answer: I found no visible damage or corrosion on the wiring or connector, and the voltage signal was present when tested with a noid light.

Intermediate - Requires basic electrical testing skills with a multimeter and potentially a noid light, along with the ability to safely remove and replace a fuel injector.
Cost of Waiting
Ignoring P0269 and the associated misfire will send unburned fuel into your exhaust system. This rapidly overheats and destroys your catalytic converter, turning a $50-$300 fuel injector job into a $800-$2,500 catalytic converter replacement.
While You're In There...
These seals are removed and often damaged during injector replacement. Replacing them prevents fuel leaks and ensures a proper seal.
A misfiring injector can foul the spark plug. If the plugs are due for replacement, it's efficient to do it while accessing the area.
Tools You'll Need
- OBD-II Scan Tool
- Multimeter
- Noid Light Set
- Fuel Injector Puller (for direct injection engines)
- Socket Set
- Wrench Set
- Screwdriver Set
- Stethoscope (optional, for listening to injectors)
P0269 is a common fuel system code. Most repairs involve replacing a single fuel injector, which is a straightforward job for an intermediate DIYer. Your engine will run smoothly again once fixed.

Your Next Steps
Step 1: Visually inspect the wiring and connector for cylinder 3's fuel injector. Look for any cuts, chafing, or corrosion. Ensure the connector is securely seated.
Step 2: If the wiring looks good, use a multimeter to test the resistance of the cylinder 3 fuel injector. Compare this reading to the manufacturer's specifications or to a known good injector on another cylinder. If the resistance is out of spec, replace the injector.
Step 3: If resistance is good, use a noid light to check for a pulse at the injector connector while cranking the engine. If there's no pulse, the problem is upstream in the wiring or the Engine Control Module (ECM). If there is a pulse, but the injector isn't clicking, the injector is likely mechanically stuck or clogged. Parts you'll likely need: A new fuel injector for cylinder 3, and potentially new injector O-rings.
